php网站编程中有关用户留言以及回复等的html代码到数据库代码
大家好,本人刚接触php,有个问题一直困扰着我,就是网站中那些论坛中,有人留言,在留言的基础上又有人对此留言进行回复的那种,就是这些html代码到php代码,再到数据库的代码,有没有相关的例子。

还有一个就是购物网站中,那些购物之后,付费,然后数据库中保存等的代码,我在哪里能够学习到啊?

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
